Another option that I don't think has been mentioned in this thread is the use of a double pole / 4 terminal cutoff switch like a Longacre 45780 or 45782 (for higher output alternators). It solves the problems of a constantly "hot" alternator wire / solenoid drain.

If I were to change over I would go with this switch..
I always like the KISS way of doing things

Decent solution. It is more money than a CD and 180 amp master switch
But with way less stuff that can fail... I'll take
the KISS way every time

And if one side of that component fails...
It's two components built into one switch. It's still controlling two circuits. You can still wire around one side in an emergency.
Pick your parts, pay your money.

I understand that its basically 2 switches but from
the guys that I know running it they havent had any
failures in at least 6 years( and still going)..
I had a failure in a constant duty solenoid in a
matter of a few weeks on my Rampage.. I replaced it
but bought a spare to carry with me

I have a similar switch on my Dart. Two poles are large and two are smaller. The larger ones have the + cable running over that side of the switch. The smaller ones have 3 wires coming off the switch going to three different relays. 1 for a relay that supplies current to the MSD box and 2 wires go to the relays at the fuel pumps. Flip the switch and the engine and both fuel pumps shut down immediately. Very simple and not much current in the three wires going to the relays. Plus I have a 300A fuse in the + cable before the switch and a 5A fuse for the smaller wires. Pretty simple and effective.
